Study Result:  Increase Free Testosterone in Just 7 Days
1:  Professional Strength Testosterone Booster is formulated with a concentrated and precise dose of boron, which is shown in human clinical research to increase free testosterone in just 7 days.  Free testosterone is the most active form of testosterone and is critical to initiating the process of muscle building.*

Maintain Peak Test to Cortisol Ratio & Enhance Performance*
2:  Professional Strength Testosterone Booster is also scientifically engineered with Rhodiola crenulata and Ginkgo biloba.  In a 7-week human clinical study, subjects taking this combination maintained peak testosterone to cortisol ratio after an intense training regimen.  While testosterone is important to keeping your body in a muscle building state, cortisol is a hormone released due to stress from training and can break down muscle tissue.  Test subjects also enhanced performance as determined by a marker of training capacity.*

Professional Strength Testosterone Booster is manufactured according to GMP standards, as is required for all dietary supplements.
